Shielding assembly

Abstract

A shielding assembly ( 100 ) comprises a circuit board ( 10 ), a shielding frame ( 20 ), and a ground plate ( 30 ). The circuit board ( 10 ) has a plurality of ground contracts ( 16 ). The shielding frame ( 20 ) is disposed to the circuit board ( 10 ). The ground plate ( 30 ) is mounted between the circuit board ( 10 ) and the shielding frame ( 20 ), and has a plurality of pins ( 36 ) connected with the ground contracts ( 16 ).

1 . A shielding assembly, comprising:
 a circuit board having a plurality of ground contracts;   a shielding frame disposed to the circuit board; and   a ground plate mounted between the circuit board and the shielding frame, and having a plurality of pins connected with the ground contracts.   
   
   
       2 . The shielding assembly as claimed in  claim 1 , wherein the circuit board has a plurality of electronic components disposed thereon. 
   
   
       3 . The shielding assembly as claimed in  claim 2 , wherein the shielding frame includes a side wall defining a chamber for accommodating the electronic components. 
   
   
       4 . The shielding assembly as claimed in  claim 3 , wherein the ground plate has a shape corresponding to the shape of the shielding frame and includes an inner side and an outer side, the pins extending from one of the inner side or the outer side. 
   
   
       5 . The shielding assembly as claimed in  claim 3 , wherein the shielding assembly further includes a shielding can engaged with the shielding frame. 
   
   
       6 . The shielding assembly as claimed in  claim 5 , wherein the shielding includes an upper plate and a securing wall protruding from the peripheral wall of the upper board, the securing wall engaged with the side wall. 
   
   
       7 . The shielding assembly as claimed in  claim 1 , wherein the ground plate is made of an elastic metal. 
   
   
       8 . The shielding assembly as claimed in  claim 7 , wherein the elastic metal is beryllium bronze or nickel alloy 
   
   
       9 . The shielding assembly as claimed in  claim 7 , wherein the pins tightly contact the ground contracts and the pins are elastically deformed so the pins are electrically connected with the ground contracts by elastic force.
